Sarudzo ye Refractory Brick Lining muZvikamu Zvakasiyana zveBlast Furnace

Iyo blast furnace parizvino ndiyo huru yekunyungudutsa midziyo, ine hunhu hwekugara zvakanaka kweveruzhinji uye hukuru hwekugadzira. Refractory brick lining inotora nzvimbo yakakosha mumoto unoputika. Nekudaro, mukuita kwekugadzira, iyo refractory zvidhinha lining yemadziro echoto inoshatiswa zvishoma nezvishoma nekuda kwemabasa akasiyana. Nokudaro, kuitira kuti uwedzere hupenyu hwebasa rehuni hwekupisa, zvakakosha kusarudza refractory brick linings zvinonzwisisika. Iyo yekusarudza nzira yerefractory zvidhinha lining yechikamu chimwe nechimwe ndeiyi inotevera:

(1) Huro yechoto inonyanya kukanganiswa nekukanganisa uye kupera kwechaji. Kazhinji, zvidhinha zvesimbi kana mvura yakanyoroveswa zvidhinha zvinoshandiswa.

(2) Kana mavhiri emazuva ano mahombe anoputika atora zvimiro zvakatetepa-madziro, zvigadziriso zvinoramba zvine makemikari zvinopikisa uye kusapfeka zvinofanirwa kusarudzwa. Pakati pavo, zvidhinha zvepamusoro-density yevhu ndiyo inonyanya kukodzera uye inowanzoshandiswa kutsiva zvidhinha linings.

(3) Iyo nzira yekukuvadza inonyanya kupisa kupisa kutyisa, kupisa kwakanyanya kwegasi, kunaya kwesimbi alkali, zinc uye kabhoni, uye kurwisa kwemakemikari kwekutanga slag. Iyo mbiru yezvidhinha inofanira kugadzirwa nezvinhu zvinoramba zvichidzivirira kutyisa kwekushisa, kunyura kwekutanga kwe slag uye kusagadzikana kwekuora. Kudzidzira kwakaratidza kuti pasinei nokuti chinhu chinoramba chakanaka sei, chinofanira kuparadzwa. Chete kana kuenzana kwasvika (inenge hafu yehupamhi hwepakutanga) inogona kudzikamiswa. Panguva iyi akanga atova makore matatu. Muchokwadi, sintered aluminium kabhoni zvidhinha nekuita zvirinani (zvakachipa zvakanyanya) zvinogona zvakare kuzadzisa ichi chinangwa. Naizvozvo, aruminiyamu-kabhoni zvidhinha inogona kushandiswa mukuputika kwefurnaces ye3m1000 uye pasi.

(4) Chikonzero chikuru chekukuvadzwa kwedumbu rechoto ndiko kukukurwa kwegasi rinopisa uye slag iron. Kupisa kuyerera kwesimba rechikamu ichi kwakakwira zvakanyanya, uye hapana refractory zvinhu zvinogona kurwisa refractory zvinhu kwenguva yakareba. Hupenyu hwesevhisi hwezvinhu zvinoramba muchikamu ichi hahuna kureba (1 ~ 2 mwedzi kureba, 2～3 mavhiki mapfupi). Kazhinji, zvinhu zvekuramba zvine refractoriness yakakwira, tembiricha yekunyorovesa yakakwira uye yakawanda yakawanda density inosarudzwa, senge yakakwira alumina zvidhinha uye aluminium kabhoni zvidhinha.

(5) Furnace tuyere nzvimbo. Iyi nzvimbo ndiyo yega oxidation reaction zone muchoto chinoputika, uye tembiricha yepamusoro inogona kusvika 1900-2400 ℃. Kushushikana kwekupisa kunokonzerwa nekupisa kwepamusoro, kukwira kwegasi, kunyura kwesimbi, alkali metal erosion, cyclic movement coke erosion, nezvimwe zvinokonzeresa kukuvadzwa kwezvidhinha. Mafuro emazuva ano anoputika anoshandisa zvidhinha zvakasanganiswa kuvaka iyo tuyere nzvimbo yemoto. Zvishandiso zvakakwirira alumina, corundum, mullite, brown corundum, silicon nitride uye silicon carbide macomposites, uye zvakare inogona kushandiswa kune inopisa-yakadzvanywa kabhoni mabhuroko.

(6) Munzvimbo umo mutsara wemoto unoputika wakasvibiswa zvakanyanya, chiyero chekuora chakagara chiri chikonzero chekugadzirisa hupenyu hwebasa rechizvarwa chekutanga chemoto. Mumazuva ekutanga, nekuti pakanga pasina kutonhora, pasi pechoto chinoputika chainyanya kushandisa imwe ceramic refractory material. Naizvozvo, izvo zvinokonzeresa zvakanyanya kukuvadzwa ndeyekutsemuka kwemasoni kunokonzerwa nekupisa kwekushushikana uye kuyerera kwezvidhinha zvepasi kunokonzerwa nekupinda kwesimbi yakanyungudutswa mumitswe, kupinda nekuora kwesimbi yakanyungudutswa pazvidhinha zvekabhoni, kurwisa kwekemikari kwesimbi alkali pa. kabhoni zvidhinha, uye kukanganisa kwekupisa kwekushushikana pane kabhoni zvidhinha. Kuparadza uye oxidation yekabhoni zvidhinha ne CO2 uye H2O zvichiri zvinhu zvakakosha izvo zvinotyisidzira hupenyu hwebasa revira revira nemoto.

Mamiriro ekugadzirwa kwechikamu chega chega chemoto unoputika akasiyana, saka nzvimbo dzakasiyana dzinofanirwa kusarudza zvakasiyana-siyana zvekuramba uye kuzvishandisa nenzira kwayo kudzivirira matambudziko asina kufanira achikonzera kuti zvinhu zvinoramba zvichitadza kuzadzisa zvinodiwa uye mamwe matambudziko.
